RAILVIAY-RAIL SPLICE.

Specification of Letters Patent. .Patented Dec. 14, 1909.

application filed April 15, 1907.v Serial No. 368,322.

To all whom it-may concern:

Be it known that I, lsnanr. NoAH PRENO- VICE, a citizen of the United States, and a resident of. the city of New York, in the county of New iork and State of New York, have invented certain new and useful Improvements in Railway-Rail Splices,-of which the following is a specification.

My inventidn relates to improvements in. railway-rail splices,,and the main objects of; myinvention are, first, to make the splice stronger to resist bending, than the splices commonlyused; second, to make the splice uncommonly stiff, so as to reduce the deflection of the rail-ends at the joint to a minimum; third, to provide a simple and cheap "construction for locking the bolts, washers and nuts, used in the splice; and fourth, to prevent by means of the splice-plates a lateral displacement and a bodily longitudinal creeping of the rails.

'l attain my objects by the construction illustrated in the accompanying drawing forming part of this specification, in which-, Figure 1, is an elevation, and Fig. 2, a cross-section of the splice; Figs. 3 and 4, show the bottom flanges 4-4, of the spliceplates in a somewhat modified form, Fig. 3, showing the same, cylindrical on their external sides and Fig. 4, showing the said flanges, elliptical on their external sides. 5, shows in 16785-2-4, a cross-section of one of the splice-plates, shown in Figs. 1 and 2, all shaped, and in 167-9 (the part 79, dotted), .the form of the splice-plate, as received from the rolls.

Like numerals designate corresponding parts in all the figures.

The splice consists of two plates, exactly -alilne and interchangeable .with each other,

the plates making when bolted up in place, as shown in the drawings, a girder like splice with three flanges to eachsplice-plate. The

top-flange 11, and the bottom flanges 4- 1, I

of the splice-plates, are conveniently located both in -relation to the neutral axis of the latter, and to the central line of the rails, to efficiently resist bending, and the great depth of the splice-plates. between the said flanges makes the splice also very stiff vertically. The middle flanges 62, 6-42, of the splice-plates, envelop the lower flanges of the rail-ends,- and are adapted to insure a great stiffness of the jointlaterally. The

top flange 1, and the continuous with the same upright member 16, of each spliceplate, are of the ordinary fish-plate angleplate shape. The flange .1, may have the continuous rib 3, on its. external side, as

shown in the drawings. The said rib is not new as such, but it is well placed to properly engage the bolt-heads 11, or the washers 12, and the nuts 14, the latter by means of the frames 13, and to efficiently resist bending,

as a part of the top flanges 1l, of the two splice-plates, located symmetrically to the central line of the rails. The middle flange 6 2, of each splice-plate, is in. general also of a commonly known form, except the continuous rib 2, and the adjacent to the latter continuous notch 5, which are new. The principal object of the ribs 2-2, and the notches 55, of the middle flanges is to avoid atightening up of the. longitudinal ,ed es 2%24, of the bottom flanges of the ral s between the oblique and horizontal members of the said middle flanges, at the bends 7-8, where such a tightening up could seriously interfere with the longitudinal sliding of the rail-ends, due to the expansion and contraction of the rails by changes in the temperature.

The bottom flanges ll, of the splice plates, are embedded into the ballast, when on a ballastedroadbed; they are in, a free space, on certain street-car tr'acksand on some bridges, where no ballast is used. I prefer to give to these flanges a prismatical or curved form on their external sides, for. in

case they are embedded into the ballast, in order to facilitate small downward and upward movements of the splice, while deflecting under the influence of the passing trains. When embedded into the ballast the bottom flanges 4ll, transfer a considerable part of the wheel-loads, passing'over the joint, directly to the ballast, thus greatly re- 4 the former by the latter.

7 16, of the spl ceorder to make impossible a tightening up of There are two rows of bolts, in the e1rample. embodying my invention; one row connecting the upper'upright members 1-6, lates with each other,

i 'and with the web the rail-ends, and the members 2-4, 2-4, of the splice-plates wlth I 10 to; fit on. there'spective nuts,

tth'e nuts,

fastened to asideof'the nut, 2t is on, with was ers 12,'and the nuts 14, the

, g locked by the;bottom"'sur 20 second row, connecting the lower upri ht each other. The heads 11, of the bolts 10 (up or bolts), and the corresponding latter in connection with the frames 13, ma been'- gaged and positively locked by the ribs 3-3, of the to" flanges, and the heads 16, of the bolts-15. lower bolts), and the corresponding nuts-1 8, the latter in connection with the I ositively.

franieujlfimay be enga ed'and Y aces of t e middle flanges 2 -8, of the splice-plates (I havensedno washers-with the bolts 15).

The frames 131and 17, if used, aremade and are pntaon after the iatter have been-all tightened up' and one of their faces made arafll'el to the corresponding locking face. he frames fill the-space between the-lockingface and theadjacent faces of the nuts, which latter are thus prevented from turning. 4 .When in. vposition, each frame is a tapibolt, either-the hole in he frame, or thatxin'the nut, being tap ed; There must be, one extra hole provide inteach nut,-as a provision for the,case,,that the face of the hat with ahole in it, may.haippen to the one, which isnea" ocking faceof the correslpond'ing. lice plluate, and thus not be availa le. for-us e;"thre'e' flanged splice is fixed in position either by having the bottom flan es 1-4, of its plates, embedded into the allast, in case of'a ballasted 'roadbed, or by having the ends 25-25, of the plates engaged by the two ties, ad'acent' to the joint, in ease, where the bottom anges are in a free space. The ovalholes 22, in

the web of the rail-end 20, as dotted in Fig. -1, indicate the commonly known provision,

for the required longitudinal sliding of the said rail-end, due to the expansion and contraction of the corresponding rail, by changes in the temperature. I

The frames 13 and 17, are made of wrought iron-or steelbars; they are of a very simple make, and are adapted to be easily fastened 'to and taken off the nuts.

While I have shown and described only one example of the physical embodiment of my invention, I do not intend to limit the" scope of my invention to this one example. I-wantit to be understood, that many changes may be made, in the detail of the (AM. i
